This is a Phase II clinical trial testing the use of two antigen-directed therapies, inotuzumab and blinatumomab, as part of induction therapy for children and young adults with newly diagnosed B-cell precursor acute lymphoblastic leukemia and lymphoma. Primary Objective * To assess if the flow-cytometry assessed MRD-negative remission rate following an immunotherapy-based Induction in NCI-high risk patients without favorable genetic features is higher than the results of similar patients treated on AALL1131. Secondary Objectives * To compare flow-cytometry assessed MRD-negative rates at the end of Induction for patients treated with this therapy compared to similar patients treated on TOT17. * To compare the rate of significant toxicities in patients treated with this therapy to those treated with standard-risk therapy on TOT17. * To assess the event free and overall survival of patients treated with this therapy.

PHASE2
This study utilizes a single arm phase II design. Treatment will consist of 3 main phases: Induction, early post induction \[including Consolidation, Blinatumomab 1, High-Dose Methotrexate, Reinduction, Interim, Reconsolidation, and Blinatumomab 2\], and Maintenance. Induction: * Induction includes 7 days of therapy on the INITIALL classification protocol (NCT06289673) as well as 5 further weeks of treatment on this trial. Treatment includes 15 days of oral (PO) or intravenous (IV) dexamethasone, 3 weekly doses of vincristine IV, and 2 doses of inotuzumab IV on Days 2 and 8. Patients will then receive blinatumomab IV from Days 9-36. Dasatinib PO will be added beginning on Day 12 for patients with an ABL-class fusion including patients with Ph+ ALL. These patients will also receive dasatinib in all subsequent cycles of therapy. Intrathecal (IT) MHA will be given. Patients will have a week without chemotherapy at the end of Induction, although patients with Induction failure (MRD ≥5% disease) will proceed directly to consolidation. Early Post Induction: * Consolidation will be given following completion of Remission Induction Therapy. Patients receive cyclophosphamide intravenous (IV), cytarabine IV, inotuzumab IV, and dasatinib PO for patients with ABL-class fusion. Patients will have a week without chemotherapy at the end of Consolidation. * Blinatumomab 1 will be given for four weeks to all patients after recovery from Consolidation. * High-dose Methotrexate will be given IV every two weeks for four cycles. Patients will also receive an intrathecal chemotherapy treatment with each of the 2 week cycles and will take oral mercaptopurine continuously if tolerated. * Reinduction will consist of dexamethasone for 7 days in the first and third week, 3 weekly doses of vincristine IV, 1 dose of daunorubicin IV, 1 dose of calaspargase IV, intrathecal (IT) MHA one dose, and dasatinib PO daily (for patients with ABL-class fusion). * Interim includes mercaptopurine po daily for 6 weeks, dexamethasone for 1 week (5 days), daunorubicin and vincristine IV on day 1 of weeks 2 and 5, calaspargase IV on day 1 of weeks 1 and 4, IT MHA on day 1 of week 4 and dasatinib po daily for 6 weeks (for patients with ABL-class fusion). Patients will have a week without chemotherapy at the end of Interim Therapy. Patients with Down syndrome will not receive daunorubicin during this phase. * Reconsolidation will repeat therapy given in Consolidation but replace the investigational inotuzumab with traditional mercaptopurine. * Blinatumomab 2 will be given for four weeks to patients with elevated end of induction MRD and patients with Down syndrome after Reconsolidation. Maintenance therapy follows Reconsolidation or Blinatumomab 2 (for those patients receiving this therapy) and includes 8 pulses of dexamethasone and vincristine given every 4 weeks, weekly methotrexate, daily mercaptopurine, intrathecal therapy, and dasatinib (for patients with ABL-class fusions). Maintenance therapy lasts a total of 80 weeks. Duration of therapy is approximately 2¼ years. Follow-up is recommended until the patient is in remission for 10 years and is at least 18 years old.
